These hPD-1 ELISA kits are immunodetection tools for measuring the levels of hPD-1 in biological samples. hPD-1 is an alias of the human PDCD1 gene, which encodes the protein, programmed cell death 1. Notably, hPD-1 is known to play a role in adaptive immune responses and the apoptotic pathway, among other functions. The PDCD1 protein is described to be 288 amino acid residues in length and 31.6 kilodaltons in mass. It is localized to the cell membrane of the cell. This protein is known to be N-glycosylated, ubiquitinated and phosphorylated. Other names for this target antigen include CD279, PD-1, and PD1.
